Zach is first seen saving Carley's life in this episode, after she opens a supply closet at a gas station containing his undead father. He cries over killing his father and is then seen in the car on the way out of the small village.

Zach is first seen sleeping in the back of Carley's van. He is awoken by her rapid acceleration to get away from Carley. He jumps over and soon begins to drive, causing an argument with Carley. Later, when the gas runs out, Carley and Zach have another argument. But, as the group are saved by Louise, Gord and Doug, Zach looses his footing and falls through the back doors and into the pit of walkers.

Zach started off being sour towards Carley, as she was the reason he had to kill his undead father. The pair had two arguments before he died. Although Carley did not like Zach, she would rather him be alive and dead, for Harrison's sake.
